Systems, methods and computer program products for providing access to web services via device authentication in an IMS network
An IP Multimedia Subsystem (IMS) network provides access to Web services. A HyperText Transfer Protocol (HTTP) message addressed to a Web Service Provider along with the IMS identifier from a device is received in the IMS network. The IMS network validates registration of the device. The IMS identifier and the HTTP message are communicated to the Web Service Provider. A Web service is conveyed from the Web Service Provider to the device.
1. A method of operating an internet protocol multimedia subsystem network to provide access to web services, comprising:
performing operations as follows, by a processor:
receiving a hypertext transfer protocol message addressed to a web service provider along with an internet protocol multimedia subsystem identifier from a device;
validating registration of the device in the internet protocol multimedia subsystem network responsive to receiving the hypertext transfer protocol message; then
communicating the internet protocol multimedia subsystem identifier and the hypertext transfer protocol message to the web service provider via a secure communication link outside of the internet protocol multimedia subsystem network responsive to validating registration of the device; and
conveying a web service from the web service provider to the device, wherein communicating the internet protocol multimedia subsystem identifier and the hypertext transfer protocol message to the web service provider comprises:
adding the internet protocol multimedia subsystem identifier for the device to a header portion of the hypertext transfer protocol message; and
transmitting the hypertext transfer protocol message to the web service provider.
2. The method of claim 1 , wherein validating the registration of the device comprises:
querying a home subscriber server database to determine if the device has registered with the internet protocol multimedia subsystem network.
3. The method of claim 1 , wherein the internet protocol multimedia subsystem identifier is an internet protocol multimedia subsystem private identity.
4. The method of claim 1 , wherein communicating the internet protocol multimedia subsystem identifier and the hypertext transfer protocol message to the web service provider comprises:
formatting a simple object access protocol message to comprise the internet protocol multimedia subsystem identifier for the device; and
transmitting the simple object access protocol message with the hypertext transfer protocol message to the web service provider.
5. The method of claim 4 , wherein transmitting the simple object access protocol message with the hypertext transfer protocol message comprises:
digitally signing the simple object access protocol message and the hypertext transfer protocol message in the internet protocol multimedia subsystem network; and
transmitting the simple object access protocol message with the hypertext transfer protocol message comprising the digital signature via the secure communication link outside of the internet protocol multimedia subsystem network.
6. The method of claim 1 , wherein transmitting the hypertext transfer protocol message comprises:
digitally signing the hypertext transfer protocol message in the internet protocol multimedia subsystem network; and
transmitting the hypertext transfer protocol message comprising the digital signature via a secure communication link outside of the internet protocol multimedia subsystem network.
7. The method of claim 1 , wherein the device is an internet protocol device.
8. The method of claim 1 , wherein the internet protocol multimedia subsystem identifier is an internet protocol multimedia subsystem public identity.
9. A method of operating a web service system, comprising:
performing operations as follows, processor: receiving a simple object access protocol message that comprises an internet protocol multimedia subsystem identifier for a device and a hypertext transfer protocol message from the device via a secure communication link outside of an internet protocol multimedia subsystem network;
identifying the device via the internet protocol multimedia subsystem identifier at the web service system; and
providing a web service to the device via the internet protocol multimedia subsystem network responsive to the identification of the device, wherein communicating the internet protocol multimedia subsystem identifier and the hypertext transfer protocol message to the web service provider comprises:
adding the internet protocol multimedia subsystem identifier for the device to a header portion of the hypertext transfer protocol message; and
transmitting the hypertext transfer protocol message to the web service provider.
10. The method of claim 9 , wherein the internet protocol multimedia subsystem identifier is an internet protocol multimedia subsystem private identity.
11. The method of claim 9 , wherein the hypertext transfer protocol message comprises a header portion, the header portion comprising the internet protocol multimedia subsystem identifier.
12. The method of claim 9 , wherein the internet protocol multimedia subsystem identifier is internet protocol multimedia subsystem public identity.
13. An internet protocol multimedia subsystem network, comprising:
a server comprising a web-services control function to receive a hypertext transfer protocol message addressed to a web service provider along with an internet protocol multimedia subsystem identifier from a device, to validate registration of the device in the internet protocol multimedia subsystem network responsive to receiving the hypertext transfer protocol message, and then to communicate the internet protocol multimedia subsystem identifier and the hypertext transfer protocol message to the web service provider via a secure communication link outside of the internet protocol multimedia subsystem network responsive to validating registration of the device, wherein communicating the internet protocol multimedia subsystem identifier and the hypertext transfer protocol message to the web service provider comprises:
adding the internet protocol multimedia subsystem identifier for the device to a header portion of the hypertext transfer protocol message; and
transmitting the hypertext transfer protocol message to the web service provider.
14. The internet protocol multimedia subsystem network of claim 13 , further comprising: a home subscriber server database; wherein the web-services control function is to query the home subscriber server database to determine if the device has registered with the internet protocol multimedia subsystem network.
15. The internet protocol multimedia subsystem network of claim 13 , wherein the web-services control function is to format a simple object access protocol message that comprises the internet protocol multimedia subsystem identifier for the device and to transmit the simple object access protocol message with the hypertext transfer protocol message to the web service provider.
16. The internet protocol multimedia subsystem network of claim 15 , wherein the web-services control function is to digitally sign the simple object access protocol message and the hypertext transfer protocol message in the internet protocol multimedia subsystem network and to transmit the simple object access protocol message with the hypertext transfer protocol message comprising the digital signature via a secure communication link outside of the internet protocol multimedia subsystem network.
17. The method of claim 13 , wherein the web-services control function is to digitally sign the hypertext transfer protocol message in the internet protocol multimedia subsystem network and to transmit the hypertext transfer protocol message comprising the digital signature via the secure communication link outside of the internet protocol multimedia subsystem network.
